Back to original languageAbout Sofiene
With over 15 years of experience in cybersecurity and complex project management, I undertake strategic missions combining governance, security, cloud, and digital transformation. At the intersection of functional and technical challenges, I support organizations in implementing security policies (ISO 27001, NIST) and regulatory requirements. I also manage and lead strategic projects (IPTV, IAM, Cloud, AdTech...). My approach combines methodological rigor with a strong results orientation.
